line m passes through point (2,-7) and (4,-9). line m is parallet to which line?

a. y= -x+2

b. y= x-9

c. x=7

d. y=-1

y= -x+2

Step-by-step explanation:

given that line m, passes through (2,-7) and (4,-9)

(refer to attached)

slope of line m,

= [(-7) - (-9)] / (2- 4)

= (-7 +9) / (2- 4)

= (2) / (-2)

= -1

recall that the general form of a linear equation is

y = mx + b, where m is the gradient.

in this case, we found that m = -1, so look for the answer where the x-term has -1 as a coefficient, i.e the x-term is "-x"

By observation, we see that the only answer that has "-x" as part of the equation is A
